For a formal treaty, you are right.. but the president can speak on issues and all but commit us to a course of action simply by his words. I think the specific wording of this amendment would assure that NO ONE but congress can make any agreements dealing with US currency.

I do like it, but think more thought should be put into it. Otherwise, I am afraid an active court may get into it later on and establish a different reading of the presidents power to make treaties based on this amendment's bad wording....
